sei-m1 No. 72ste@ particularly to a new' and improved con-` struction ot said bumper that is especially designed and adapted tl'or application to and use in connection with the well known Ford automobile, and similar auti'miobilcs that are structurally characterized by the provision ot a trout body bolster and semi-elliptic spring,l centrally united and both disposed in the vertical plane 'of the front axle, and a radiator frame supported on said body bolster; n automobiles of this type,y the problem involvled in the structural form and mode of attaclnncnt of a bumper is by no means as simple as in the case ot' the more usual type ot automobiles that are characterized by the provision ot forwardly extending knuckles which constitute an easy and practically obvious point oit attachment. My invention and its mode of application to the automobile 'front will be readily understood when considered in connection with the acconipanying drawings, in which# Figure 1 is a perspective elevation olthc front pt )rtion of a Ford automobile showing my improved bumper applied thereto, the bumper bar being broken out between its ends to disclose parts lying;- there behind'; and Fig. 2 .is a side perspective elevation of one ot' the carrying larms of the bumper bar and its parts.

Referring to the drawings, 5 designates the radiator frame, 6 the front axle, and T the front wheels of an automobile of the Ford type.

8 is the front spring, of the se1ni-elliptic type, disposed above and in the vertical plane of the -tront axle 6 and suitably articulated thereto at its ends, as shown. Restingr centrally upon the spring .8 and secured thereto by a central clamp 9, 1s the upwardly curved front body bolster 10, the ends oil which engage beneath and are bolted to laterally extending lugs 11 on the sides ot' the radiator frame 5.

Referring now to my improved bumper, 12 designates the main forwardly projecting portion ofeach of a pair of lnversely disposed bumper-bar carrying-arms. The outer end portion of each arm is formed by a rod 13 that telescopes within the tubular lorward end of the main section 12 and is Surrounded by a cushhming spring' lll. The rod 1 3 is confined against displacement lby a pin 1:1 at its inner end playing through a` slot 16 in the barrelcd forward portion oi' the arm section 12; and on the outer end of the rod 13 1s a clamp 17 to which the usual transversely extending bumper-bar 18 is sel cured. y

',lhe lower or inner portion of the arm scction 12 is bent inwardly substantially at a right angle, said portion being' shown at '19 and terminating` in a horizontal yoke 1nember 2() that is adapted to snugly straddle the body bolster l() and spring S at one side ot the center ot'said parts. and preferably adn jacent to the end of the central clamp 9. The arms of the yoke 2O are apertured at 21 to. receive abolt 22, the yoke 20 and bolt 22 -thus unitedly forming a clamp for rigidly securimer the inner end of the arm to the bolster and spring'. Preferably, and as herein shown, the bumper-bar carrying-arms are braced to the radiator `frame by means of brace-bars Q3, each of which is riveted at 24 to the main section 12 of themarm, and, at4

its opposite end, secured to ono of the lateral lugs 1l ot` the radiator' frame by means of a bolt Q5 which may conveniently be the same bolt that is used to connect the radiator trame to the body bolster.

The described construction provides a `very simple, strong, inexpensive and easily applied bumper for automobiles of' t-he type specified.
